In accordance with Scheme III, compounds of formula 3 are N-alkylated inthe presence of formaldehyde and either a primary amine such asmethylamine, ethylamine, benzylamine, methyl glycinate, (L or D)alanine,(L or D)lysine or their substituted congeners; or a secondary amine suchas morpholine, pyrrolidine, piperidine or their substituted congeners togive the corresponding Mannich base adduct, 4.

The 9-[(substituted glycyl)amido]-6-demethyl-6-deoxytetracyclines may beobtained as metal complexes such as aluminum, calcium, iron, magnesium,manganese and complex salts; inorganic and organic salts andcorresponding Mannich base adducts using methods known to those skilledin the art (Richard C. Larock, Comprehensive Organic Transformations,VCH Publishers, 411-415, 1989). It is well known to one skilled in theart that an appropriate salt form is chosen based on physical andchemical stability, flowability, hygroscopicity and solubility.Preferably, the 9-[(substitutedglycyl)amido]-6-demethyl-6-deoxytetracyclines are obtained as inorganicsalt such as hydrochloric, hydrobromic, hydroiodic, phosphoric, nitricor sulfate; or organic salt such as acetate, benzoate, citrate, cystsineor other amino acids, fumarate, glycolate, maleate, succinate, tartrate,alkylsulfonate or arylsulfonate. Depending on the stochiometry of theacids used, the salt formation occurs with the C(4)-dimethylamino group(1 equivalent of acid) or with both the C(4)-dimethylamino group and theW group (2 equivalents of acid). The salts are preferred for oral andparenteral administration.

Some of the compounds of the hereinbefore described Schemes have centersof asymmetry at the carbon bearing the W substituent. The compounds may,therefore, exist in at least two (2) stereoisomeric forms. The presentinvention encompasses the racemic mixture of stereo isomers as well asall stereoisomers of the compounds whether free from other stereoisomersor admixed with stereoisomers in any proportion of enantiomers. Theabsolute configuration of any compound may be determined by conventionalX-ray crystallography.

The stereochemistry centers on the tetracycline unit (i.e. C-4, C-4a,C-5a and C-12a) remain intact throughout the reaction sequences.

BIOLOGICAL ACTIVITY Method for in Vitro Antibacterial Evaluation (TablesI, II and V)

The minimum inhibitory concentration (MIC), the lowest concentration ofthe antibiotic which inhibits growth to the test organism, is determinedby the agar dilution method using Muller-Hinton II agar (BaltimoreBiological Laboratories). An inoculum density of 1×5×10⁵ CFU/ml and arange of antibiotic concentrations (32-0.004 μ/ml) is used. The platesare incubated for 18 hours at 35° C. in a forced air incubator. The testorganisms comprise strains that are sensitive to tetracycline andgenetically defined strains that are resistant to tetracycline, due toinability to bind to bacterial ribosomes (tetM) or by a tetK encodedmembrane protein which confers tetracycline resistance byenergy-dependent efflux of the antibiotic from the cell.

E. coli in Vitro Protein Translation System (Table III)

An in vitro, cell free, protein translation system using extracts fromE. coli strain MRE600 (tetracycline sensitive)and a derivative of MRE600containing the tetM determinant has been developed based on literaturemethods [J. M. Pratt, Coupled Transcription-translation in ProkaryoticCell-free Systems, Transcription and Translation, a Practical Approach,(B. D. Hames and S. J. Higgins, eds) p. 179-209, IRL Press,Oxford-Washington, 1984].

Using the system described above, the tetracycline compounds of thepresent invention are tested for their ability to inhibit proteinsynthesis in vitro. Briefly, each 10 μl reaction contains S30 extract (awhole extract) made from either tetracycline sensitive cells or anisogenic tetracycline resistant (tetM) strain, low molecular weightcomponents necessary for transcription and translation (i.e. ATP andGTP), a mix of 19 amino acids (no methionine), ³⁵ S labeled methionine,DNA template (either pBR322 or pUC119), and either DMSO (control) or thenovel tetracycline compound to be tested ("novel TC") dissolved in DMSO.

The reactions are incubated for 30 minutes at 37° C. Timing is initiatedwith the addition of the S30 extract, the last component to be added.After 30 minutes, 2.5 μl of the reaction is removed and mixed with 0.5ml of 1N NaOH to destroy RNA and tRNA. Two ml of 25% trichloroaceticacid is added and the mixture incubated at room temperature for 15minutes. The trichloroacetic acid precipitated material is collected onWhatman GF/C filters and washed with a solution of 10% trichloroaceticacid. The filters are dried and the retained radioactivity, representingincorporation of ³⁵ S-methionine into polypeptides, is counted usingstandard liquid scintillation methods.

The percent inhibition (P. I.) of protein synthesis is determined to be:##EQU1## In Vivo Antibacterial Evaluation (Table IV)

The therapeutic effects of tetracyclines are determined against an acutelethal infection with Staphylococcus aureus strain Smith (tetracyclinesensitive). Female, mice, strain CD-1 (Charles River Laboratories), 20±2grams, are challenged by an intraperitoneal injection of sufficientbacteria (suspended in hog mucin) to kill non-treated controls within24-48 hours. Antibacterial agents, contained in 0.5 ml of 0.2% aqueousagar, are administered subcutaneously or orally 30 minutes afterinfection. When an oral dosing schedule is used, animals are deprived offood for 5 hours before and 2 hours after infection. Five mice aretreated at each dose level. The 7 day survival ratios from 3 separatetests are pooled for calculation of median effective dose (ED₅₀).

Testing Results

The claimed compounds exhibit antibacterial activity against a spectrumof tetracycline sensitive and resistant Gram-positive and Gram-negativebacteria, especially, strains of E. coli and S. aureaus containing tetMresistance determinants, and E. coli containing the tetA, tetB, tetC andtetD resistance determinants. Notable is9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline, CC, asshown in Table I, which demonstrated excellent in vitro activity againsttetracycline resistant strains containing the tetM resistancedeterminant (such as S. aureus UBMS 88-5, S. aureus UBMS 90-1 and 90-2,E. coli UBMS 89-1 and 90-4) and tetracycline resistant strainscontaining tetB resistance determinants (such as E. coli UBMS 88-1 andE. coli TN10C tetB).9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline, also hasgood activity against E. coli strains containing tetA, tetC and tetDresistance determinants. It is as effective as minocycline againstsusceptible strains and is superior to minocycline against a number ofrecently isolated bacteria from clinical sources. (Table II)

As shown in Table II, the free base, disulfate, dihydrochloride,monohydrochloride and the Mannich bases of9-[(N,N-dimethylglycyl)amino]-6-demethyl-6-deoxytetracycline, showcomparable in vitro antibacterial activity.

Minocycline and9-[(N,N-dimethylglyoyl)amido]-6-demethyl-6-deoxytetracycline are assayedfor their ability to inhibit protein synthesis taking place on eitherwild type or TetM modified ribosomes using a coupled transcription andtranslation system. Both compounds effectively inhibit protein synthesisoccurring on wild type ribosomes, at equivalent levels of activity.Minocycline is not effective in inhibiting protein synthesis occurringon tetM modified ribosomes. In contrast,9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline iseffective at inhibiting protein synthesis occurring on TetM modifiedribosomes, although a slightly higher concentration is required toachieve similar levels of inhibition relative to wild type ribosomes.(Table III)

9-[(N,N-Dimethylglycyl)amido]-6-demethyl-6deoxytetracycline bindsreversibly to its target (the ribosome) since bacterial growth resumeswhen the compound is removed by washing of the organism. Therefore, theability of 9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracyclineto inhibit bacterial growth appears to be a direct consequence of itsability to inhibit protein synthesis at the ribosome level.

As shown in Table IV, the claimed compounds AA, BB, DD, CC, H, C, D, Gand Q show very good in vivo activity when tested intravenously againstthe minocycline sensitive organism, S. aureus Smith. The claimedcompound CC when administered intravenously exhibits potent activity(ED₅₀ 1.6 mg/kg) against E. coli UBMS 90-4 (TetM), which is resistant tominocycline, i.e. (ED₅₀ >32 mg/kg).

As shown in Table V,9-[(N,N-dimethylglycyl)amido)]-6-demethyl-6-deoxytetracycline showspotent in vitro antibacterial activity against a broad spectrum ofrecent clinical isolates, including a number from veterinary sources. Itwas more active than minocycline and tetracycline against the majorityof the isolates tested. The claimed compound is especially activeagainst E. facecalis, E. faecium including vancomycin resistant strains.The 9-[(dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline alsoexhibits potent activity against E. coli, Salmonella spp., Shigellaspp., Salmonella choleraesuis, Proteus mirabilis, Proteus vulgaris,Morganella morganii, Neisseria gonorrhoeae, Bacteroides spp.,Clastridium spp. and Streptococcus spp. The activity of the9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline isgenerally greater than minocycline and tetracycline.

As can be seen from Tables I-V, compounds of the invention can be usedto prevent or control important mammalian and veterinary diseases suchas diarrhea, urinary tract infections, infections of skin and skinstructure, ear, nose and throat infections, wound infections, mastitisand the like.

Thus, the improved efficacy of9-[(N,N-dimethylglycyl)amido]-6-demethyl-6-deoxytetracycline isdemonstrated by the in vitro activity against isogenic strains intowhich the resistance determinants, such as tetM, are cloned (Table I);the inhibition of protein synthesis by TetM modified ribosomes (TableIII); and the in vivo activity against experimental infections caused bystrains resistant to the tetracyclines, due to the presence ofresistance determinants, such as tet M (Table IV).

When the compounds are employed as anti-bacterials, they can be combinedwith one or more pharmaceutically acceptable carriers, for example,solvents, diluents and the like, and may be administered orally in suchforms as tablets, capsules, dispersible powders, granules, orsuspensions containing, for example, from about 0.05 to 5% of suspendingagent, syrups containing, for example, from about 10 to 50% of sugar,and elixirs containing for example, from about 20 to 50% ethanol and thelike, or parentally in the form of sterile injectable solutions orsuspensions containing from about 0.05 to 5% suspending agent in anisotonic medium. Such pharmaceutical preparations may contain, forexample, from about 25 to about 90% of the active ingredient incombination with the carrier, more usually between about 5% and 60% byweight.

An effective amount of compound from 2.0 mg/kg of body weight to 100.0mg/kg of body weight should be administered one to five times per dayvia any typical route of administration including but not limited tooral, parenteral (including subcutaneous, intravenous, intramuscular,intrasternal injection or infusion techniques), topical or rectal, indosage unit formulations containing conventional non-toxicpharmaceutically acceptable carriers, adjuvants and vehicles It will beunderstood, however, that the specific dose level and frequency ofdosage for any particular patient may be varied and will depend upon avariety of factors including the activity of the specific compoundemployed, the metabolic stability and length of action of that compound,the age, body weight, general health, sex, diet, mode and time ofadministration, rate of excretion, drug combination, the severity of theparticular condition, and the host undergoing therapy.

These active compounds may be administered orally as well as byintravenous, intramuscular, or subcutaneous routes. Solid carriersinclude starch, lactose, dicalcium phosphate, microcrystallinecellulose, sucrose and kaolin, while liquid carriers include sterilewater, polyethylene glycols, non-ionic surfactants and edible oils suchas corn, peanut and sesame oils, as are appropriate to the nature of theactive ingredient and the particular form of administration desired.Adjuvants customarily employed in the preparation of pharmaceuticalcompositions may be advantageously included, such as flavoring agents,coloring agents, preserving agents, and antioxidants, for example,vitamin E, ascorbic acid, BHT and BHA.

The preferred pharmaceutical compositions from the standpoint of ease ofpreparation and administration are solid compositions, particularlytablets and hard-filled or liquid-filled capsules. Oral administrationof the compounds is preferred.

These active compounds may also be administered parenterally orintraperitoneally. Solutions or suspensions of these active compounds asa free base or pharmacologically acceptable salt can be prepared inglycerol, liquid, polyethylene glycols and mixtures thereof in oils.Under ordinary conditions of storage and use, these preparations containa preservative to prevent the growth of microorganism.

The pharmaceutical forms suitable for injectable use include sterileaqueous solutions or dispersions and sterile powders for theextemporaneous preparation of sterile injectable solutions ordispersions. In all cases, the form must be sterile and must be fluid tothe extent that easy syringability exists. It must be stable under theconditions of manufacture and storage and must be preserve against thecontaminating action of micoorganisms such as bacterial and fungi. Thecarrier can be a solvent or dispersion medium containing, for example,water, ethanol, polyol (e.g., glycerol, propylene glycol and liquidpolyethylene glycol), suitable mixtures thereof, and vegetable oil.

The invention will be more fully described in conjunction with thefollowing specific examples which are not be construed as limiting thescope of the invention.
